我正在尝试编译 moses（机器翻译工具）。我在编译时指定了 boost 的位置，如下所示。
./bjam --with-boost=/home/xhotsuki/bin/boost_1_56_0 -j8
但是我遇到了很多这样的错误。
...failed gcc.link mert/bin/gcc-4.4.6/release/debug-symbols-on/link-static/threading-multi/timer_test...
...skipped <pmert/bin/gcc-4.4.6/release/debug-symbols-on/link-static/threading-multi>timer_test.passed for lack of <pmert/bin/gcc-4.4.6/release/debug-symbols-on/link-static/threading-multi>timer_test...

/home/xhotsuki/bin/boost_1_56_0/include/boost/test/unit_test.hpp:59: undefined reference to `boost::unit_test::unit_test_main(bool (*)(), int, char**)'
出了什么问题？
